Add dehumidifier function

[JyunWei-Su]

Add the following dehumidifier function:

• Fan operation mode select (duplicated, removed)
• Fan direction select
• Set humidity select (duplicated, removed)
• Power control switch (duplicated, removed)
• Buzzer control switch
• NanoeX control switch

Thank you, @JyunWei-Su

I have two questions:

1. Since the humidifier entity already includes power control and operation mode, do we really need separate entities for these functions?
2. Regarding the humidity select entity, should we change the operation mode to manual humidity setting before sending the command?

1. When I checked the logs, I found that my humidifier entity did not load correctly. I am not sure if this is caused by another bug, so I added two control entities (power control and operation mode) separately.

2. Regarding the humidity select entity, should we change the operation mode to manual humidity setting before sending the command?
   No, the operation mode will be automatically changed if the humidity select entity value has changed (and the command is sent).

Note: my dehumidifier model is F-Y20JH
Core version: 2024.7.2

panasonic smart app version based on 2.8.1

Hi @osk2 ,
I have fixed the humidifier.py so that it works well. #110
According to your previous suggestion, I think we DON'T need to separate entities for three functions (fan operation mode select, set humidity select, and power). I have removed the duplicated entities.

I'm going to merge this PR and do some testing.
Since I am busy with other things, this could take a while before we can release the new version.
